DESCRIPTION
The HI-8783, HI-8784, and HI-8785 are system compo-
nents for interfacing 8 bit parallel data to an ARINC 429
bus. The HI-8783 is a logic device only and requires a sep-
arate line driver circuit, such as the HI-8382 or HI-8585.
The HI-8784 and HI-8785 combine logic and line driver on
one chip. The HI-8784 has an output resistance of 37.5
ohms, and the HI-8785 has an output resistance of 10
ohms to facilitate external lightning protection cicuitry. The
technology is analog/digital CMOS.
The HI-8783 is available in a 22 pin DIP format as a second
source replacement for the Micrel / California Devices
DLS-111BV.
The products offer high speed data bus data transactions
to a buffer register. After loading 4 bytes, data is automati-
cally transferred and transmitted. The data rate is equal to
the clock rate. Parity can be enabled in the 32nd bit. Reset
is used to initialize the logic upon startup. Word gaps are
transmitted automatically.
The HI-8784 and HI-8785 require +/- 10 volt supplies in ad-
dition to the 5 volt supply.
